Hello. I have extensive experience with React/Node.js. I am ready for collaboration.
Project: MVP crypto-casino with the game Crash
Goal: Create a working version of a mini-casino with one game (Crash), registration via email and nickname, acceptance of cryptocurrency, Provably Fair, and a basic admin panel.
Registration:
Form with 2 fields: email, nickname
Uniqueness of the nickname, email validation
Login via email (session storage through JWT)
Email confirmation is not required for MVP
Ability for automatic login on re-entry (token storage)
Game: Crash
The user places a bet and clicks "Start"
The coefficient increases (example: 1.00x, 1.12x, 1.45x...) until a random crash
The player can "cash out" the bet before the crash (win = bet * coefficient)
If they are too late — the bet is lost
Provably Fair:
A hash of the result is shown before the game
After — seed and crash multiplier
Player's betting history
Balance and crypto:
The player sees the balance in USDT
Generation of a unique deposit address
Tracking incoming transactions to the address
Automatic balance crediting upon transaction confirmation
Withdrawal: through the admin panel or via a button with confirmation (by email or manually)
Admin panel:
User table (email, nickname, balance)
Search by email/nickname/address
View bets, deposits, and withdrawals
Button "Block player"
Ability to process withdrawals manually
Stack (preferred):
Frontend: React.js + Tailwind CSS
Backend: Node.js (Express or Nest.js)
DB: MongoDB or PostgreSQL
Wallets: Web3.js / Ethers.js or BlockCypher API (for monitoring)
Auth: JWT
Bonus:
It is preferable to use a proven algorithm for fair RNG
Ready-made UI templates can be used (for example, Tailwind UI or Figma)

Hello! I have reviewed your technical assignment — the task is very interesting and quite feasible at the MVP level. I suggest implementing the project from scratch using a modern stack, as transparently as possible, with the potential for further scaling.
🔧 What I will do:
I will implement registration via email and a unique nickname, JWT authorization with auto-login.
I will create the main mechanics of the Crash game — coefficient growth, the ability to cash out the bet, random crash.
I will integrate Provably Fair mechanics with the generation and verification of seeds and hashes.
User balance in USDT, with the generation of a unique deposit address (via Web3.js / Ethers.js).
Automatic balance replenishment after transaction confirmation.
A basic admin panel for tracking deposits/bets/withdrawals with the ability for manual withdrawals and player blocking.
A fully responsive frontend on React + Tailwind with the ability to use.
I will use PostgreSQL or MongoDB depending on scalability requirements.
📌 From my side:
The code will be clean, modular, and ready for development.
All basic improvements after launch will be included in the cost.
I will provide technical support for launch and hosting (if necessary).
I can offer additional features if needed (chat, player leaderboard, game history output, etc.).
I would be happy to discuss the details and timelines. I am ready to start immediately after agreement!

The audience is already created, but is currently updated manually. The executor is required to: Propose the optimal implementation method. Specify what accesses and permissions will be needed. Estimate the cost and time for completion. Indicate experience working with Meta API and Make. After setup, provide a brief description of the logic of operation and the accesses used. Additionally, please clarify: is a complete daily replacement of the audience possible through the API and what limitations or risks may exist from Meta's side.

When placing an order, when the buyer selects the country "Ukraine," the system substitutes the delivery method from the "Rest of the World" zone (Self-pickup (M)) instead of the "Ukraine" zone (Self-pickup (U)). The shipping plugin support has already tested this hypothesis: they deactivated the UA Shipping plugin, turned off all its delivery methods, and left only the standard WooCommerce methods — The problem remained even after this, meaning the cause is not in the shipping plugin, but somewhere in the site settings.
